摘要： An optical fiber connector for connecting the ends of two optical fibers has a connector body made of a highly elastic material. The connector body has end faces and a lateral outer surface. A fiber conduit extends along a longitudinal axis of the connector body. The conduit is adapted to receive one or more optical fibers. The connector includes a shouldered fiber slot extending longitudinally between end faces of the connector body. The shouldered slot has a narrow portion extending radially outwardly from the fiber conduit and a wide portion extending radially inwardly from the outer surface. The wide portion of the shouldered slot has inwardly facing surfaces upon which opposing lateral forces can be applied for causing the shouldered slot to expand for receiving the optical fibers. The lateral opposing forces can be applied orthogonally to a radial direction defined by the shouldered slot.

摘要： The present invention is directed to an optical fiber connector for fiber lasers having improved signal conduction which minimizes optical losses. This optical fiber connector is capable of operating at high power levels, by dissipating heat and by maintaining the alignment of the optical fibers even when the fibers thermally expand in the presence of high temperature. The connector may be made of a shape memory alloy having a generally cylindrical body and a longitudinal conduit for splicing together the optical fibers.

摘要： An optical fiber phase modulator has a body made of a shape memory alloy. The body includes a conduit for receiving an optical fiber. An actuator such as, for example, a piezoelectric transducer varies the constrictive (radially compressive force) applied by the conduit on the optical fiber to modulate the phase of the optical signal carried by the optical fiber. A fiber Bragg grating (FBG) incorporating this novel tunable phase modulator may be used in distributed feedback (DFB) fiber lasers and narrow band pass filters. This invention also provides a tunable birefringent phase modulator, which may be used in fiber polarization switches. The shape memory alloy phase modulator does not require glue to connect the fiber to the actuator and, consequently, this novel modulator does not suffer the optical losses that typical arise with prior-art devices nor is it prone to breakage as are the more fragile bonded devices.

摘要： The present invention comprises a connector comprising shape memory material such as a shape memory alloy, an optical fiber conduit and an axial stress opening traversing the connector from the connector surface to the fiber conduit and along at least a portion of a longitudinal length of the connector. The fiber conduit is dimensioned for optical fibers and to secure two optical fibers in abutment alignment for light signal transmission from one fiber to the other, with minimal attenuation and for securing the fibers without crushing or other damage to the fibers. In another embodiment, the present invention relates to a method of bringing optical fibers in abutment connection for signal conduction using a connector as above, wherein a wedging force is applied to the stress opening, whereby the wedging force will induce separation of the side walls of the slot and expansion of the fiber conduit for insertion of optical fibers and their abutment connection and securing of the fibers in abutment connection, when the wedging force is removed. Alternatively, a force may be applied to either side of the stress opening to again expand the opening and fiber conduit for the purpose of placement of optical fibers within the fiber conduit. Removal of the force will allow retention of the fibers in abutment connection of the fibers. In a still further embodiment, the present invention relates to an apparatus which applies a wedging force to a stress opening for expansion of a fiber conduit and insertion of optical fibers and their retention, light transmission abutment and connection in a connector as above.
